VAPORIZER FORv INTERNAL-COMBUSTION ENGINES.

Application filed .Tuly 6,

The object of my invention is to provide a vaporizer for .internalcombustion engines of simple7 durable and comparatively inexpensiveconstruction.

More particularly, my invention relates to an attachment wherein asupply of water may be fed into a heating` chamber, a small amount at atime wherein the steam created in the heating chamber may then be drawninto the intake manifold of the engine.

Still a further object is to so mount the heat-ing chamber relative tothe reservoir` that only a drop or two of water is permitted to flowfrom the reservoir to the heating chamber at a time.

With these and other objects in view, my y invention consists in theconstruction, ar rangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claim, and illustrated in theaccompanying drawings, in which Figure 1 is a side View of an internalcombustion engine with my improved vaporizer device installed therein.

Figure 2 is a top, plan view of my vaporizer device.

Figure 3 is a vert-ical, sectional view taken on line 3-3 of Figure 1;and

Figure 4 is a detail. sectional view taken on line 4-4 of Figure 2.'

In the accompanying drawings, I have used the reference numeral toindicate generally an internal combustion engine, which includes anengine block 11. the exhaust manifold 12 and an intake manifold Theengine block 11 has mounted therein a number of engine bolts 14.

My improved vaporizer device includes a reservoir or tank 15 mountedupon a supporting bracket 16 which has a plurality of openings 17therein. The engine bolts 14 extend through the openings 17 and anchorthe reservoir 15 on tok the engine block 11, as clearly shown in Figure1 of the drawings.

A supporting brace 18 is fastened to the reservoir 15 and is connectedto a bolt 19, which is'mou'nted in the engine block 11. The reservo-ir15 has a screw threaded neck 2Q, which serves as an opening throughreserve li925. seriai No. 41,472.

A screw threaded cap 21 coacts with the neck for serving as a closuremember for the reservoir.

A washer 22 is interposed between the cap 21 and the neck 20. as clearlyshown in Fig- The heating chamber 24 has a pair ofl `,brackets 25extending on. one side thereof,

which have openings 26.

The engine bolts 14 extend through the` openings 26 and serve to retainthe heating chamber in position on the exhaust manifold vof water may beshut ofi' from the chamber 23. The chamber 23 is positioned below thebottom of the reservoir so that water from the reservoir 15 will 'passinto the chamber gravity, as will hereinafter be more fully set forth.

Secured to the cover plate 27 is a fitting 31 which has a closing valve32 therein.

' A pipe 33 connects the fitting 31 and is tapped into the intakemanifold 13, as clearly shown in Figure 1 of the drawings.

An air inlet opening 34 is formed in the coverl plate 27.

The reservoir 15 is designed to be air tight so that. when the level ofthe water within the chamber 23 reaches the point indicated by thereference numeral 35. then no additicnal amount of water will flow intothe chamber 23 because aseal will be formed,

The water within the chamber 2,3 will bef come heated and the steamtherefrom will be drawn into the intake manifold 13, and as the steam iscreated, the water within the chamber 23 willy be .used up and a smallamount of additional water will pass then fron reservoir into thechamber cau'sethe water level in the chamber 1"will below the point e5,thereby admitting ffii air to the tube 28 in the form of bubbles 8Gwhich, duefto :their buoyancy travel upwardly and into the reservoir l5ythereby displacing a small amount ot Water which vat one time is verysmalliso that the heat of the Water Within the chamber will bemaintained at a boiling point at practically. all times.

l`When it is desired not'ito hayevanymoisture enter through thev intake,manifold then all that la; necessary ie to turn the valyc member 32 toclosed position.

Somev changes maybeimade inthe con- .pstiuction and arrangement ot'xthevarious parteI of, my .invention7 Without -vdeparting from the real,Spirit andpurpoee of my invVention, andit is myintention'to cover by myclaim, any modilied torina ot structure or use ot mechanical equival iLe, which may be reasonably included within' its Scope.

I claim as my invention:
